EDGE- TRIMMING ATTACHMENT FOR LAWN MOWERS Filed Nov! 10, 1928 I PatentedJune 10, 1930 a v UNITED STATES PATENT OFFICE trimming the edges oflawns,gardens,' paths, walks and the like and the general object of theinvention is to provide a trimmer of ,this. character which may bereadily attachedtoa lawn mower or readily removed i therefrom, whichwhen. attached to the lawn qflmower does not have to be removed when 1the mower is used for ordinary work and x which will not interfere withthe free trundling of the lawn mower to and from the work and which atthe same time may be readily removed if necessaryi s further object isto provide a trimmer I 1.5 of this character which when in use is forceda, throughthe sod, at the edge of the lawn or path, by the wholeweightof the mower but i which is balanced against lateral canting or aWtilting movement by traction wheels supaaportedupon the shaft on whichthe cutting disk is mounted. i Other objects will appear inthe oourseofthe following description.

invention is illustrated in the panying drawings, wherein 2-- i i Figure:1 is aside elevation of a lawn mower with my attachment appliedthereto; Figure-2 is a like view to Figure 1 showing a y the mowerinverted and the attachment in 3c use;

Figure 3 is a plan view'of the attachment, the mower handle being shownin section.

Referring to the drawings, it will beseen that I have illustrated a.lawn mower ofj ordinary type having the usual handlelO ex tendingordinarily downward and forward i and connected bythe yoke bars 11 tothe main axle for the traction wheels 12. The

accomusual roller 13i'smounted upon the brackets Q projecting rearwardfrom the main frame Y J and the main frame includes the transverse "rod1 1,.commonly found on machines of this character. 4 All ofthesepartsmay be of any 1 usual or suitable construction and it will be:}understood that I have illustrated any common and ordinary type oflawn mower.

My attachment comprises a pair of arms y 15 which are pivoted upon atransverse rod 1 i 16 which is inserted through the handle 10 50.:zandthrough the upper ends of the yoke bars This invention relates totrimmers used in disk and the arms 15 but in relatively wide lawn mowersthree of these rollers will be 3 used and in very narrow lawn mowerspos- ANDREW n.

11, this rod passing through the opening ordinarily provided for one ofthe transverse bolts holding theyoke bars to the handle. The extremitiesofthe transverse bar or rod 16 are reduced and provided with nuts 17preventing any lateral movement of the arms 15. The arms 15 at theirfree ends carry a transverse shaft 18 and the nuts 19 and mounted uponthis transverse shaft for movement therearound is a sleeve 20. carryinga cutting disk 21. having a diameter of. five or six inches thoughobviously I do not wish to be limited thereto.

. Alsomounted upon this shaft at each end a of the sleeve 20 are therollers 22 which rotatefreely upon the shaft independentlyof the disk 2land'are spaced from each other..

I have illustrated twoof these rollers 22 on each side of the disk, thatis, between the sibly only two rollers will be necessary. These rollersare designed to restupon the grass or upon the margin of the lawn anduponthe walk while the disk 21 operates to trim the grass or sod at theedge of thepath.

Bracing thearms 15 from each other is a transverse rod 23 and for thepurpose of holding the attachment raised and inlinoperative position, Iprovide any suitable latch as forinstance the latch illustrated inFigure 1 comprising a head 24:, a shank 25 extending through the handleof the mower, and a spring 26 urging the shank inward. The headisundercut on its inner face so that when the attachment is turned backagainst the handle, the head may be drawn out against theaction of thespring 26 and then turnedi to engage overthe rod 23, thus locking theattachment raised. By this means also the attachment may be readilyreleased for use. s i

In the use of the device, the attachment is i turned downward and thenthe lawn mower is reversed so that the roller 13 and the cutting knivesare upward. The disk 21 and the rollers 22 will, under these circumstances, support the whole weight of the lawnmower so that the weight ofthe lawn 100 I WQ [act tgi foicej the v(mtting disk 21 l to thevisod,the. extent oflthiseuttihg action I being" limited-i-by Ithe .efontact0fgthe -ii011e1fs 1 V 22 iwith the sod or' withi the sod and; surface 7fthep ath. .j
